The next step is to create C++ classes representing a node (Node class) in a phylogenetic tree (Tree class).
We will then modify main.cpp to create a Tree object.
| Step | Title | Description |
| Step 2.1 | Create the Node Class | Declare the |
| Step 2.2 | Create the Tree Class | Declare the |
| Step 2.3 | Create the main function | Define the |
| Step 2.4 | Test Node and Tree | Test the new |
